Graphitelektrode (HP grade)

HP graphite electrode Grade: HP Dia:150mm-800mm Length:1100mm-2100mm Electric resistance:5.5-7Ω Product sortGraphite electrode can be divided into ordinary power, high power and ultra high power electrode by electrode quality index.1. Graphite electrode of ordinary power Allowable used graphite electrode with current density lower than 17A/cm2, mainly used in ordinary power electric furnace for steel-making, silicon smelting and yellow phosphorus smelting.2. Graphite electrode with oxidation resistant coating Graphite electrode with oxidation resistant coating has protective layer which can conduct electricity, heat resistant and anti-oxidation, reduce the electrode consume when steel-making.3. Graphite electrode of high powerAllowable used graphite electrode with current density lower than 18-25A/cm2, mainly used in high power arc furnace for steel-making.4. Graphite electrode of ultra high powerAllowable used graphite electrode with current density lower than 25A/cm2. Mainly used in ultra high power arc furnace for steel-making.
